USN/UK subs have same "low" buoyancy reserve all the time. Statistically they should be sunken in accidents more often than russian subs.

That is a faulty assesment, because if you look at the losses of the subs they were due to the causes that were independent from boyancy reserves where those were availiable (ie excluding charlie class for example).
In fact in one such case (loss of the Mike class) the loss can be attributed to a feature that improves survivability to combat dammage (solid fuel gas generators for emergency blow), that feature is currently standard on Soviet/Russian desighns.
To recap my point - double hull and boyancy reserves allow the submarine to survive certain types of combat dammage (lightweight torpedo hit with a single compartment flooding) unlike the classical single hull, poorly compartmentalised US desighns without reserves, but does not magically make that sub unsinkable (though Oscars and Typhoons are as close to that as possible).
Nor does it affect the reliability and safety of the desighn, which is a separate matter entirely.
